SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 517,577, dated April 3,1894. Application filed May 4, 1893. Serial No. 472.963. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES S. LEE, a citizen of the United States,residing in Troy, in the county of Rensselaer and State of New York,have invented a new and useful Sash Stop and Tightener for Windows, ofwhich the following is a specification.

My invention relates to improvements in sash stops for windows and theobjects of said improvement are, first, to make the window when closedperfectly tight thereby keeping out cold air and dust and in winterdoing away with the necessity of storm sash; second, to obviate thedifficulty of raising or lowering the sash when it swells or the stop isset tight against it; third, to prevent the rattling of the sash whenloose in the frame or by the shrinking of the stop; fourth, toaccomplish the several objects automatically. I attain these objects bythe mechanism illustrated in the accompanying drawings, in which- Figure1 is a view of the stop and sash in place. Fig. 2 is a view of the stopand sash separate. Fig. 3 is a view of the lug by which the stop isdrawn downward. Fig. 4 is aview of the spring by which the stop isthrown upward. Fig. 5 is a view of the outside and stationary part ofthe stop. Fig. 6 is a view of the inside and movable or adjustable partof the stop. Fig. 7 is a section through a. a. Fig. 1.

Similarletters refer to similar parts throughout the several views.

The stop consists of two pieces B and O. The piece B being movable andhaving two or more slots G diagonal to B. slides downward and forwardandvice versa in the rabbeting of the stationary pieceO as the sash israised or lowered. The rabbeting of the piece 0 and the window frameforming a box for the piece B to move in. Attached to the lower frontedge of the sliding piece B is a lug D and under B is fastened a springE. When the notch F cut in the lower corners of the sash (Fig. 2)strikes upon the lug D the stop is drawn downward and forward againstthe sash and forces it outward against the parting stop I thus makingthe window tight and noiseless. When the sash is raised the spring Ethrows the stop B up and backward from the sash leaving it free tobemoved and thus obviating the source of trouble caused by the swelling ofthe sash or otherwise as is often the case when the stop is immovablysecured to the frame of the window as in the stop now universally used.

The rabbeted piece 0 of the stop is provided with bushings which pa sthrough the slots G. in the slide B thereby forming bearings for theslot G to slide upon and through these bushings the screws pass whichsecures the whole stop to the frame of the window and keep the screwsfrom drawing the piece 0.

against the slide B. thereby preventing its working. The bushings arenot however necessary to the working of the device and do not constitutean element of the invention as the stop B. can slide upon the screwspassing through the slots G.

The notch F. shown in Fig. 2 is cut into the lower inside corner of thesash a sufficient depth to allow the lug D to pass to its seat at thetop of the notch and the notch is out high enough from the lower edge ofthe same so that when the sash is drawn down to its seat the stop B willhave been drawn down and forward against the sash thus stopping allrattle of the sash and making every part tight. It is made to workautomatically by means of the notch F., the lug D., the slots G. and thespring E.

I do not limit myself to any particular form of either of the members ofthis device as they may be varied to suit the style of window where theyare to be used without departing from my invention. They may also bemade of wood, metal or any other material that will accomplish theresults to be attained.

I am aware that window sash stops and tighteners have been inventedconsisting of twoor more parts one or more of the parts being movableand worked by the moving of the sash but they do not relieve the sashfrom pressure while being raised or lowered the pressure being constantthereby producing friction and wear on the stop and sash and 3. Thecombination of the movable part 13 having diagonal slots G with the lugD and spring E all for the purposes herein specified. 15
